Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.

A unique laboratory at Michigan Tech captured microscopic photography of snowflakes in a demonstration of the lab's high-powered scanning electron microscope. The Applied Chemical and Morphological ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

The Thermo Fisher Apreo 2 Variable Pressure Field Emission Scanning Electron Microscope (FE-SEM) is a thermionic field emission high-resolution scanning electron microscope. The Apreo 2 FE-SEM is an ...

Support grids are a key part of electron microscopy measurements; the choice of the grid can directly influence the quality and accuracy of the final image. This is particularly true for transmission ...
